List of alarms
Last modified:
The following tables describe the alarms (error codes) generated by blue’Log. When an alarm is triggered, the information is sent via email or sent to VCOM. See Alarm/state configuration.
Note
For a full list of alarms that can be read via the SCADA interface, see the SCADA interface data sheet and register: Downloads - meteocontrol GmbH.
System alarms
Error code | Description | Closes when? | Recommendation |
|---|---|---|---|
ALARM_DB_FULL | Alarm database is full / device alarming was deactivated | When there is enough free space: the oldest entries are deleted the following day. | Check the detected alarms and contact the device manufacturer if necessary for further clarification. |
EXTERNAL_POWER_DISPLAY | The maximum pulse rate of 16 Hz was exceeded | Resolved | Choose a smaller number of impulses per kWh. |
MAX_POWER_EXCEEDED | Maximum allowed total power exceeded | Resolved | Contact the meteocontrol sales department to buy a larger license. |
PASSWORD_FORGET | Password forgotten triggered | Resolved | Check your email inbox and enter the code you received in the blue'Log. In addition, enter a new password. |
Device and device communication alarms
Error code | Description | Closes when? | Recommendation |
|---|---|---|---|
NOCOMM_RS485 | Communication failure (RS485) | Resolved | Check if the device is working, if there is a cable connection or if the communication interface of the device is configured / activated correctly. |
NOCOMM_TCP | Communication failure (TCP) | Resolved | Check if the device is working, if there is a cable connection or if the communication interface of the device is configured/activated correctly. |
NOTIMPL_FEAT_GET_VALUE | Get value not supported | Resolved | Contact meteocontrol support. |
NOTIMPL_FEAT_PC | Power control not supported | Resolved | Contact meteocontrol support. |
NOTIMPL_FEAT_SCAN | Device scan not supported | Resolved | Contact meteocontrol support. |
NOTIMPL_FEAT_SET_VALUE | Set value not supported | Resolved | Contact meteocontrol support. |
NOTIMPL_FEAT_START_STOP | Start/Stop not supported | Resolved | Contact meteocontrol support. |
STATUS | Abnormal state | Resolved | None |
Power control alarms
Error code | Description | Closes when? | Recommendation |
|---|---|---|---|
MQTT_CONNECTION_FAILED | At least one slave has failed to connect to master XC: Not all slaves are connected XM: The connection to the master failed to be established | Immediately, if Resolved alarms/states toggle is activated. See Alarms/state. | Check the network connection between master and slave for interruptions, faults. |
MQTT_CONNECTION_LOST | At least one slave has lost the connection to master | Immediately, if Resolved alarms/states toggle is activated. See Alarms/state. | Check the network connection between master and slave for interruptions, faults. |
CABLE_BREAKAGE | Setpoint value cannot be determined as cable breakage was detected | Resolved or PC restarts | Check configuration and interface for setpoint command via analog signal (0/4 ... 20 mA). |
FEED_IN_METER_FAILURE | Actual value for measured value feedback is missing | Resolved or PC restarts | Check meter configuration and interface for recording of utility measurements. |
GRID_DISCONNECT | Automatic grid disconnection tripped | Resolved or PC restarts | Check the power control settings if automatic grid disconnection occurs too frequently. |
LFSMO_ACTIVATED | Limited frequency sensitive mode - overfrequency (LFSM-O) activated because the actual system frequency is above the configured frequency threshold | Immediately after P control goes back into normal operation. For this, the Resolved alarms/states toggle must be activated. See Alarms/state. | None |
LFSMU_ACTIVATED | Limited frequency sensitive mode - overfrequency (LFSM-U) activated because the actual system frequency is under the configured frequency threshold. | Immediately after P control goes back into normal operation. For this, the Resolved alarms/states toggle must be activated. See Alarms/state. | None |
P_SET_POINT_MISSING | Setpoint value for active power control is missing | Resolved or PC restarts | Check configuration and interface for active power setpoint commands. |
Q_SET_POINT_MISSING | Setpoint value for reactive power control is missing | Resolved or PC restarts | Check configuration and interface for reactive power setpoint commands. |
SYSTEM_FALLBACK | Fail-safe operation was activated, and a system fallback value is used as setpoint until a valid setpoint is received | Immediately, if Resolved alarms/states toggle is activated. See Alarms/state. | Check configuration and interface for setpoint command or change mode for behaviour in event of error. |
TRANSMITTER_FAULT | Setpoint value cannot be determined as transmitter fault (overcurrent) was detected. | Resolved or PC restarts | Check configuration and interface for setpoint command via analog signal (0/4 ... 20 mA). |
